Traction Gantry Home Elevator System Price is one of the most important considerations when planning a residential elevator for a villa, private house, duplex, self-built home, or low-rise residential building. However, the purchase price of a home elevator is rarely determined by the elevator car alone. The final project budget can include the traction system, gantry structure, elevator car, controller, doors, safety components, shaft or enclosure, structural work, electrical installation, transportation, commissioning, inspection, and long-term maintenance.
